Modbus and Nibe Modbus40

[merel]

I am connecting to the Nibe Modbus 30 heat pump in next month on a project. Anybody has a good script for it and want to share ?

This is my example modbus json definition for modbus Visual mapper.
                                                                         
Good luck.
